The strangest thing happend to me early this morning.?

Around 3:00am my carbon monoxide detectors went off and i jumped out bad faster then i had ever jumped out of bed before. After i started walking to check the alarm, i lost all hearing, I literally went deaf for about 2 minutes and mt stomach hurt like it never hurt before, I did everything i could from throwing up. Is this normal or was this just a freak thing that occurred? Also, I felt completely fine when i woke up later this morning and all day today.
